DETAILED DESCRIPTION

The electrical apparatus 1 for an electrical installation (FIG. 5), able and intended to be connected to an electrical grid, comprises at least:

-   -   a primary functional module 2 comprising a first connection pole         3 able and intended to be connected to a first line L of the         electrical grid, a second connection pole 4 able and intended to         be connected to a second line L1 of an electrical circuit of the         electrical installation and a third connection pole 40 able and         intended to be connected to a third neutral line N of the         electrical grid (FIGS. 1B and 5),

the primary functional module 2 being able and intended to perform a function of interrupting the current between the first connection pole 3 and the second connection pole 4 and comprises a control member 2′ such that, in an open position, an electrical circuit between the first connection pole 3 and the second connection pole 4 is open (FIG. 5) and that, in a closed position, the electrical circuit is closed (FIGS. 1A and 1C),

-   -   an additional functional module 5 comprising means for         performing at least one function requiring an electric power         supply, comprising at least a fourth connection pole 6 and a         fifth connection pole 7 that are electrically connected         respectively to the first connection pole 3 and to the third         connection pole 40 of the primary functional module 2 in order         to supply power to the additional functional module 5 (FIGS. 2A         to 2E, 3B and 5),     -   a reception module 8 comprising at least a first reception area         9 for receiving the primary functional module 2 (FIGS. 3A to 4).

According to the invention, the electrical apparatus 1 is characterized in that the reception module comprises a second reception area 9′ for receiving the additional functional module 5 (FIG. 3A),

and in that said at least one function of the additional functional module 5 is a function requiring an electric power supply, excluding a lighting function.

The excluded lighting function is understood to mean a lighting function that is implemented by way of an indicator light able and intended to be turned on both when the control member 2′ is in the open position and when the control member 2′ is in the closed position. For example, when the primary functional module 2 controls a load 20, such as lighting, the indicator light is always turned on both when the lighting is not supplied with power and is therefore turned off and when the lighting is supplied with power and is therefore turned on. This type of lighting function excluded from the invention is most often used to locate and identify an electrical apparatus 1 in darkness in part of a building (not shown), such as a stairwell (not shown).

Advantageously, the electrical apparatus 1 makes it possible to perform, in addition to the function of interrupting the basic current performed by the primary functional module 2, at least one additional function using the additional functional module 5. Such an additional functional module 5 thus allows the electrical apparatus 1 to be customized. Furthermore, as the additional functional module 5 is optional, it is able to be installed or removed at any time without impacting the electrical installation. Specifically, the electrical apparatus 1 is able to operate only with the primary functional module 2. The electrical apparatus 1 that is obtained is thus particularly flexible. Moreover, the additional function of the additional functional module 5 is not intended to inform the user about the location or the state of the interruption function, but advantageously extends to functions independent of the interruption function.

The electrical apparatus 1 is preferably intended to be assembled with or recessed into a support (not shown), such as a wall.

The primary functional module 2 may be a monostable switch module (not shown) or a bistable switch module (FIGS. 1A to 1C). In the case of a monostable switch module, in the open position, the control member 2′ does not act on the opening of the electrical circuit and, in the closed position, the control member 2′ may be designed to close the electrical circuit; in this configuration, the monostable switch module is also called “normally open”. According to one alternative of a monostable switch module, in the open position, the control member 2′ may be designed to open the electrical circuit and, in the closed position, the control member 2′ does not act on the closure of the electrical circuit; in this configuration, the monostable switch module is also called “normally closed”. The control member 2′ of a monostable switch module may preferably be a pushbutton (not shown).

For a bistable switch module, shown in FIGS. 1A to 1C, in the open position, the control member 2′ may be designed to open the electrical circuit and, in the closed position, the control member 2′ may be designed to close the electrical circuit. In this case, the control member 2′ may preferably be a toggle switch that is able to adopt two positions. However, this example is not limiting.

The primary functional module 2 comprises a first connection pole 3 able and intended to be connected to a first line L of the electrical grid, a second connection pole 4 able and intended to be connected to a second line L1 of an electrical circuit of the electrical installation and a third connection pole 40 able and intended to be connected to a third neutral line N of the electrical grid (FIG. 5).

The first line L may be a power supply line connected to the electrical grid, preferably via a switching device, such as a circuit breaker.

The second line L1 may be a return line for supplying power to a load 20 of the electrical installation, such as lighting (FIG. 5).

The first line L, the second line L1 and the third neutral line N may take the form of one or more cables (not shown).

The electrical installation may preferably be a domestic electrical installation.

Said at least one function of the additional functional module 5 may be chosen, alone or in combination, from among a function of measuring at least one physical parameter and/or an electromagnetic radiation transmission and/or reception function and/or a display function and/or an actuation function and/or a data processing function and/or a function of transforming a physical signal into an electrical signal or vice versa.

Said at least one physical parameter may be temperature, pressure, hygrometry, brightness; these examples are of course nonlimiting.

The electromagnetic radiation transmission and/or reception function may be limited to radiofrequency electromagnetic radiation. This configuration is preferred in particular in order to allow data to be communicated from the electrical apparatus 1 to a control unit (not shown) described below.

The function of the additional functional module 5 may be able and intended to be supplied with power and activated when the control member 2′ of the primary functional module 2 is in the open position or when the primary functional module 2 is in the closed position.

Advantageously, in this configuration, the means for performing the function of the additional functional module 5 are able to be supplied with power by the electrical grid when the electrical circuit of the primary functional module 2 is open, and therefore when the control member 2′ is in the open position. As a result, when the control member 2′ is in the open position or when the electrical circuit of the primary functional module 2 is closed and therefore when the control member 2′ is in the closed position. As a result, when the control member 2′ is in the open position or in the closed position, the function of the additional functional module 5 is able to be activated. Therefore, the power supply of the additional functional module 5 is independent of the state of the primary functional module 2.

The additional functional module 5 may comprise an electrical energy storage and/or production element and the function of the additional functional module 5 may be able and intended to be supplied with power by said electrical energy storage and/or production element.

Advantageously, the function of the additional functional module 5 is able to be supplied with power by an electrical energy storage and/or production element, which may be made independent and autonomous in relation to the electrical grid. As a result, the function of the additional functional module 5 is able to be activated independently of the open or closed position of the primary functional module 2, this being particularly useful in the case of disconnection from the electrical grid.

The electrical energy storage and/or production element may be a battery, a capacitor, a piezoelectric generator, a photovoltaic generator, or a thermoelectric generator, for example a Peltier or Seebeck generator.

The additional functional module 5 may comprise at least one measurement sensor able and intended to perform said function of measuring at least one physical parameter.

The measurement sensor may be a temperature sensor, a pressure sensor, a hygrometer, a photodetector, an infrared sensor, a transducer; these examples are of course nonlimiting.

The additional functional module 5 may comprise at least electromagnetic wave transmission and/or reception means able and intended to perform said electromagnetic radiation transmission and/or reception function.

These electromagnetic wave transmission and/or reception means may be a radiofrequency communication element, for example Wi-Fi or Bluetooth, or a repeater. Of course, these examples are not limiting.

Advantageously, these electromagnetic wave transmission and/or reception means make it possible to receive and/or transmit data that may in particular relate to the additional functional module 5. Such electromagnetic wave transmission and/or reception means may, in addition, establish a wireless communication link with a control unit, such as a computer, a smartphone or a digital tablet or to another additional functional module 5 according to the invention and that would also be equipped with electromagnetic wave transmission and/or reception means. It is thus possible to interact remotely with the electrical apparatus 1.

The additional functional module 5 may comprise at least display means able and intended to perform said display function.

Advantageously, these display means make it possible to form a visual interface with a user.

These display means may be a screen.

The additional functional module 5 may comprise at least actuation means able and intended to perform said actuation function.

The actuation means may be an actuator, for example a relay, a solenoid, a micromotor, a piezoelectric mechanism or, in general, any type of means configured so as to transform an electrical quantity into a mechanical quantity or vice versa.

The additional functional module 5 may comprise at least data processing means able and intended to perform said data processing function.

The data processing means may be a microcontroller. These data processing means may, for example, make it possible to process data coming from the measurement sensor.

The additional functional module 5 may comprise at least image-capturing means, for example, a camera.

The additional functional module 5 may comprise at least one transducer able and intended to perform said function of transforming a physical signal into an electrical signal or vice versa.

The transducer may be an electroacoustic transducer, such as a speaker or a microphone.

The transducer may be a vibrator or a diffuser.

The additional functional module 5 may comprise at least one electronic card 10, 11 comprising the measurement sensor and/or the electromagnetic wave transmission and/or reception means and/or the display means and/or the actuation means and/or the data processing means and/or the image-capturing means and/or the transducer.

According to one variant embodiment of the invention, a first electronic card 10 may comprise the measurement sensor and/or the display means and/or the electromagnetic wave reception and/or actuation means and/or a transducer and/or image-capturing means and a second electronic card 11 may comprise the electromagnetic wave transmission and/or reception means and/or the data processing means and a third electronic card (not shown) may comprise the electrical energy storage and/or production element.

The first electronic card 10, the second electronic card 11 and the third electronic card may be electrically connected to one another.

The first electronic card 10 may preferably be a removable component of the additional functional module 5.

Advantageously, the function or functions of the additional functional module 5 may thus be modified simply and easily by replacing the first electronic card 10. It is thus not necessary to replace the entire additional functional module 5.

In particular, the first electronic card 10 may comprise at least first connection means 24 complementary with at least second connection means 25 of the second electronic card 11. Said connection means make it possible to electrically and mechanically connect the first electronic card 10 and the second electronic card 11 in a removable and reversible manner (FIGS. 2A and 2D).

The first connection means 24 and the second connection means 25 may consist of a USB connection, by way of non-limiting example.

The primary functional module 2 may comprise at least a first connection terminal 3′ electrically connected to the first connection pole 3 and a third connection terminal 40′ electrically connected to the third connection pole 40, and the first connection terminal 3′ and the third connection terminal 40′ may form a first outlet 13 (FIG. 1C).

The first connection terminal 3′ and the third connection terminal 40′ may be respectively a first female terminal and a second female terminal, for example taking the form of a cavity provided with electrical contact. In this case, the first outlet 13 is a socket. This first outlet 13 may preferably comprise two cavities distributed along one side of a square (FIG. 1C).

The first socket outlet 13 may preferably have a protection rating whose degree of protection against solids is between 0 and 6 and whose degree of protection against liquids is between 0 and 8. For example, the protection rating may be equal to IP2X, X being a value between 0 and 8.

The fourth connection terminal 6′ and the fifth connection terminal 7′ may be respectively a fourth male terminal and a fifth male terminal, for example taking the form of a rod. In this case, the second outlet 14 is a plug. The second outlet 14 may comprise a base 14′ from which the fourth connection terminal 6′ and the fifth connection terminal 7′ in the form of a rod extend. The base 14′ preferably has a substantially square shape with rounded corners from which four pads 14″ extending substantially orthogonal to the base 14′ extend. These pads 14″ form a mechanical joint with the first socket outlet 13, these pads 14″ being able to fit into the cavities. Two of these pads 14″ may support the two rods forming the fourth connection terminal 6′ and the fifth connection terminal 7′ (FIGS. 2A, 2B, 2C, 2E).

The primary functional module 2 may comprise a first housing 15 with which the first outlet 13 and the control member 2′ are assembled (FIGS. 1A, 1B, 1C).
